Hard wire a Sureflap cat flap with battery backup? (self.offtopic)

I've got a Sureflap cat flap operated by 4 AA batteries. It doesn't work well on rechargeables, it seems to need 1.5v batteries.

I'm thinking to hardwire it with battery backup (like a Ups). I'm not very experienced in electronics, are there any off the shelf products I could use? I'm assuming the flap runs at 6v and that I can just attach two cables, one to plus, one to min.

If there are no off the shelve products, any recommendations for what I should buy?

I was thinking this usb powered battery replacement which has a 6v option. https://a.aliexpress.com/_m030556

There's no motor, just a click system to unlock / lock the flap. And easiest would be to plug it into a power bank which is also charged at the same time by 220v.

Right so just an actuator which probably doesn't need much current
